Abstract
本实用新型涉及一种秸秆粉碎还田机专用甩刀，其结构特点是在刀刃部位焊接有硬质合金条，硬质合金条的横截面的形状为梯形或正方形或长方形。所述的硬质合金条的横截面上小下大。本实用新型的有益效果是大大提高了抗磨能力，使用寿命长，粉碎效果好，节约能源。
The utility model relates to a special throwing knife for a straw crushing and field returning machine. The structural feature is that a hard alloy strip is welded on the blade, and the cross section of the hard alloy strip is trapezoidal, square or rectangular. The cross-section of the hard alloy strip is small at the top and large at the bottom. The beneficial effect of the utility model is that the anti-wear ability is greatly improved, the service life is long, the crushing effect is good, and energy is saved.
Description
Technical field
The utility model relates to the special-purpose flail knife of a kind of straw crushing and field-returning machine, belongs to the parts cutter of agricultural machinery.
Background technology
Chinese patent discloses " a kind of straw crushing and field-returning machine blade ", and (application number: 20040075242.9), flail knife wherein is to be coated with weldering one deck with welding rod to be coated with layer on the outer surface at blade position.Though the wearability of above-mentioned flail knife increases, in actual use, the service life of flail knife is still shorter, and the forward lower comer of flail knife is easily by rounding, thereby flail knife is cut grab the ability of stalk to be affected, and causes crushing effect relatively poor.In addition, be coated with layer and make blade thickening rust, resistance increases during operation, makes power and fuel consume bigger.
Summary of the invention
Technical problem to be solved in the utility model provides that a kind of abrasion-resistance is strong, the special-purpose flail knife of straw crushing and field-returning machine of long service life, good crushing effect, the saving energy.
The technical scheme that its technical problem that solves the utility model adopts:
Design feature of the present utility model is to be welded with the carbide alloy bar at the blade position, the cross section of carbide alloy bar be shaped as trapezoidal or square or rectangular.The cross section of described carbide alloy bar is up-small and down-big.
The beneficial effects of the utility model are to have improved abrasion-resistance greatly, long service life, good crushing effect, energy savings.

Fig. 2 is the structural representation of embodiment 2 of the present utility model.
Fig. 3 is the shaft side figure (shape of cross section is trapezoidal) of carbide alloy bar,
In Fig. 1-3,1. installing hole, 2. cutter hub, 3. carbide alloy bar, 4. cutter hub.
Embodiment
Embodiment 1:
By the embodiment 1 shown in Fig. 1,3 as can be known, it is the flail knife that is provided with angle between a kind of knife edge part and the cutter hub, and being welded with shape of cross section at blade part is trapezoidal carbide alloy bar 3, the cross section of this carbide alloy bar 3 up-small and down-big (seeing Fig. 1,3).
In present embodiment 1, also can adopt cross section is trapezoidal upper and lower equally thick carbide alloy bar.
Embodiment 2:
By the embodiment 2 shown in Fig. 2,3 as can be known, it as different from Example 1 the cutter hub of flail knife be plate shaped.
In present embodiment 2, also can adopt cross section is trapezoidal upper and lower equally thick carbide alloy bar.
Embodiment 3:
Embodiment 3 is that to change the carbide alloy bar in embodiment 1 or 2 into cross sectional shape be rectangular carbide alloy bar, and the cross section of this carbide alloy bar is up-small and down-big.
In present embodiment 3, also can adopt cross sectional shape is rectangular upper and lower equally thick carbide alloy bar.
Embodiment 4:
Embodiment 4 is that to change the carbide alloy bar in embodiment 1 or 2 into shape of cross section be foursquare carbide alloy bar, and the cross section of this carbide alloy bar is up-small and down-big.
In present embodiment 4, also can adopt cross sectional shape is foursquare upper and lower equally thick carbide alloy bar.
